Engine Coolant Temperature (ECT) (°C)

The value indicates the actual engine temperature. The Engine Control Module (ECM) calculates the temperature using signals from the directly connected Engine Coolant Temperature sensor.

Measurement range: -40 - 125°C.

Normal value: With warmed up engine at idle the temperature deviates between 85 - 108°C depending on the ambient temperature.

HINT: By means of thermostat heating, temperature regulation can be demand controlled. In situations with high load and/or extremely high ambient temperature, the temperature is regulated around 15°C lower than the above normal value. 

HINT: The engine is considered to be cool after the engine has been switched off for at least 10 hours. The temperature can then be compared with the ambient temperature and the difference must not be greater than ±5°C.
